Luffy is taken by a bird and drops in a town controlled by the pirate captain Buggy the Clown, and there he meets a girl named Nami. Nami hates pirates, however, and tricks Luffy by handing him over to Buggy, and Nami is faced with a difficult choice by Buggy.

The episode opens with Nami pretending that Luffy is her boss, using the distraction to escape. She watches as Luffy takes out Buggy's pirates with a Gomu Gomu no Pistol (Gum Gum Pistol), and so she asks Luffy to join her. Luffy refuses, and Nami treats him to lunch, so he goes with her. In the restaurant, Nami says that she will stop at nothing to collect 100,000,000 Beli, and Luffy finds out she is a navigator because she mentions stealing a map of the Grand Line from Buggy. When Luffy asks her to join his crew, she refuses because she hates pirates. Nami ties up Luffy and brings him to Buggy, and Luffy is thrown into a cage. Buggy then throws a party as Nami returns the stolen map.
